How can I tell what version of Visual Studio was last used to work on a project?

Question

I\'m working with some older code, and I think the person who last built it was using Visual Studio 6. There\'s no .vcproj file, but the .dsp and .dsw files have the following h

Answer 1

I opened a VisStudio 6.0 dsw file i have, and it reads Format Version 6.00.

I opened a VisStudio 2008 sln file i have, and it reads Format Version 10.00.

So i assume so?

It corresponds. if 6.0 is version 6.0, then Visual Studio .NET (2002) is 7.0, Visual Studio .NET 2003 is 8.0, Visual Studio 2005 is 9.0, and Visual Studio 2008 is 10.00
